acts 16:33 And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway. - Free Bible Online

      33. And he took them--the word implies change of place.
      the same hour of the night, and washed their stripes--in the well or fountain which was within or near the precincts of the prison [HOWSON]. The mention of "the same hour of the night" seems to imply that they had to go forth into the open air, which, unseasonable as the hour was, they did. These bleeding wounds had never been thought of by the indifferent jailer. But now, when his whole heart was opened to his spiritual benefactors, he cannot rest until he has done all in his power for their bodily relief.
      and was baptized, he and all his, straightway--probably at the same fountain, since it took place "straightway"; the one washing on his part being immediately succeeded by the other on theirs.
